But then I would have to choose to use a different API (Futures) for this rare case. Why would I do that, when I could instead use the common streaming API and just unsubscribe when the event occurs? I agree with Brandon, given that Future can only apply with something like .once(), I doubt it is really useful to try to include Future here because part of the API would be using the traditional callbacks and another part would be using Future. The inconsistency doesn't seem to be worth it. -- Mounir
